I bought karbonn Titanium mach five 5 months ago after using it I just want to say that It is the best low budget phone available in the market right now.It has got 5mp secondary camera with Led flash which is clear enough.
Battery is long lasting, it is lightweight, looks are attractive.It has 1gb ram, it is fast & smooth functioning without lags, audio quality is good.Overall it is best phone in the budget I would recommend. Cheers ^_ ^
